Channel Timeline Viewer helps you watch YouTube channels from the beginning without losing your place. Browse a channel from its oldest uploads, track what you have watched, resume from the exact playback position, and keep notes as you go. Archives, courses and long-running series stay in order. WHO IT'S FOR • People learning from YouTube tutorials, lectures, courses, educational channels and long-running series • Anyone catching up on a channel's back catalog • Viewers who want to know exactly how far they've watched • Channel operators who want viewers to work through their older uploads in order MAIN FEATURES • Paste a channel URL, or share a video or channel from the YouTube app or Safari • Uploads listed oldest-first (or newest-first) • Per-channel progress: watched count, percentage, progress bar • "Up next / Continue" takes you straight back to where you stopped • Resume from the exact second you left off • Autoplay to the next video in the list (on by default, and you can turn it off at any time) • Repeat one or repeat all • Mark videos watched or skipped; play unwatched only • Filters: all / unwatched / watched • Search within a channel to narrow videos by title • Notes for each video, for studying or series viewing • Playback speed and captions controlled outside the player • Position shown as "February 27, 2026 (1,034 / 3,500)" • Five navigation buttons — first, previous, undo, next, last — where undo restores both the video and the position you were at • Channels you have opened before load instantly from a saved list PLAYBACK Videos play in YouTube's official embedded player (IFrame Player). FREE AND PRO You can save one channel for free. Inside that channel everything works without limits: sorting, watched tracking, resume, jump buttons, notes, progress, and playback in the official player. You can swap in a different channel for free, but doing so deletes the watched history, progress, and notes of the previous one. To follow several channels side by side and keep every record, buy Pro. It is a one-time purchase, not a subscription. PLEASE NOTE • This app is not the official YouTube app. • It does not download videos, block ads, or play in the background. • Video lists are retrieved via the YouTube Data API v3. • Autoplay is on by default, but it only moves to the next video in the list you opened, and you can turn it off on the player screen at any time. • The free version shows ads. Pro is a one-time purchase with no ads — no subscription. YouTube is a trademark of Google LLC.
